DUSENIUS PAULSON, OF FLAXTON, NORTH DAKOTA.

SHADE-ROLLER BRACKET.

Specification of Letters Patent;

Patented Mar. 2, 1920.

Application filed June 4, 1919. Serial No. 301,645.

To all whom it may concern:

. Be it known that I, DUSENIUS- PAULsoN, a citizen of the United States of America, residing at Flaxton, in the county of Burke and State of North Dakota, have invented new and useful Improvements in Shade- Roller Brackets, of Which the following is a specification.

The object of the invention is to provide a shade roller bracket which may be readily mounted and secured in place under such conditions as to efficiently support the shade roller without the use of fastening means serving to puncture, penetrate, indent, or otherwise mar or deface the window casing and with this end in view the same consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawing it being understood that changes in form, proportion and details may be resorted to within the scope of the claims without departing from the principle involved.

In the drawing:

Figure 1 is a view of a bracket applied in the operative position to a window casing and supporting one end of a shade roller.

Fig. 2 is a face view of the bracket detached from the casing.

Fig. 3 is a horizontal sectional view on the plane indicated by lines 33 of Fig. 1.

Fig. 4: is a detail view in perspective with the parts or elements of the bracket disassociated.

Essentially the bracket consists of relatively movable or separable bearing elements 10 and 11 preferably having upwardly bent shoulders forming feet 12 and 13 for contact respectively with the facing surfaces of a sash bead 1a and a parting strip 15 of the ordinary window casing indicated at 16, and an arched spreader 17 terminally engaged respectively with said bearing elements and adapted by the flattening of the arch, thus causing the separation of the terminals of the spreader to force the feet of the bearing elements into sufliciently firm contact with the surfaces of said bead and parting strip to lock the same in places. One of the bearing elements carries roller bracket arm 18 which obviously may be of any preferred construction and in practice as shown, said arm together with the attached bearing element 10 may be constructed from a blank of sheet metal as also may the element 11. The upturned portions forming the bearing feet 12 and 13 also form inner or reentrant angles constituting seats for the terminals of the spreader, and a bolt 19 fitted with a thumb nut 20 may be utilized for adjusting or flattening the spreader to lock the bracket in place.

Furthermore, in practice, it is preferable to mount the bearing elements upon a base which for convenience, may consist of a base plate 21 and a guide plate 2-2, the latter being offset intermediately to form a guide 23 of a width sufficient to receive the body portions of the bearing elements, and the adjusting bolt 19 may extend through the registry openings 24, 25 and 26 formed respectively in the spreader, the guide and the base plate and may be actuated as at 27 at the rear side of the latter as indicated in Fig. 3.

With the adjusting means loosened sufficiently to permit of an interval between the exterior surfaces of the bearing feet which is less than the interval between the surfaces of the sash beam 1 1 and parting strip 15, the device may be positioned as indicated in Fig. 3 after which the tightening of the thumb screw will cause the expansion of the spreader with the consequent forcible separation of the bearing feet to bring them into securing contact with the surfaces of the frame. The bolt 19 in addition to performing its function as an element of the extending means for the spreader serves to hold the parts of the bracket assembled, so that other means may not be required in this connection.

The invention having been described, what is claimed as new and useful is:

1. A shade roller bracket having relatively movable bearing elements provided with feet for contact respectively with the opposing faces of the elements of a casing, one of said elements carrying a bracket arm, an arched spreader terminally seated respectively upon said bearing elements and means consisting of a bolt extending through the spreader and a nut threaded upon the bolt and engaging an intermediate point of the spreader for expanding the latter to support,

the feet of the bearing elements.

2. A shade roller bracket having a base consisting of a base plate and a guide plate having registering openings, bearing elements slidably mounted in said guide and provided with upturned bearing feet, one of which is extended to form a bracket arm, a spreader plate terminally seated upon said bearing elements respectively and having an opening registering with those of the guide and base p1ate, a bolt engaging the registry openings of said base plate guide and spreader plate, and a thumb nut engaging 10 the bolt forexpandingthe pressure upon the spreader plate.

' Intestimony whereof I aflix my si ature.

DUSENIUS PAULSON.
